Q:
Why band X is not on MetalTabs? Aren't they metal?A:
There are three possibilities:

We don't have any tabs for X. You can request the tabs here.
Your band will appear on MetalTabs as soon as the tab is approved by our team unless...

We don't consider X metal. Our stance on this (rather pointless) debate is similar
to the position of
Encyclopaedia Metallum. This means that if a band
is approved at Encyclopaedia Metallum, it will be approved here as well. If you added a tab
and it was rejected by our team, your best bet is to get it listed on EM and then
re-submit your tab.

Band X is well-known for their hostile attitude towards free online tablature
or they asked us to remove their tabs from MetalTabs.
